In a meeting with Iranian Foreign Minister Hossein Amir-Abdollahian, UN Secretary-General Antonio Guterres expressed appreciation towards Iran's essential role in contributing to regional peace and security, in addition to cementing the United Nations' support for the returning of all parties to the Joint Comprehensive Plan of Action (JCPOA) in hopes of its revival. 

Amir-Abdollahian, on his part, noted the talks achieved much progress regarding lifting sanctions off Tehran as well as reviving the JCPOA. 

He reiterates that if the US acts realistically, the final agreement could be reached.

Al-Monitor published Monday that Amir-Abdollahian announced that Iran is ready to cooperate with the International Atomic Energy Agency (IAEA) on resolving the remaining issues regarding the country's nuclear activities as long as the IAEA chooses to focus on technical issues.

He stressed that "The Agency needs to behave and act technically,” rather than politically.

Secretary-General of the IAEA, Rafael Grossi, has most recently demanded Iran to offer an explanation for the "traces of uranium" that was found in non-declared nuclear sites.

Tehran, on its part, slammed the concerns as baseless, and that its nuclear program is subject to the most inclusive inspection in the history of the IAEA. 

On Monday, Grossi emphasized the need to work together to find answers to issues that exist between Iran and the IAEA and will not go away if they are not resolved.
